Title:  Galvanically isolated bidirectional current-fed dc-dc converters for battery energy storage systems

Abstract:

Massive introduction of dispersed energy generation systems imposes new challenges of grid stability due to the intermittent nature of the renewable energy sources. Energy storage systems is an attractive solution for both residential and small commercial applications. They can improve electricity supply security and electricity peak demand shaving, particularly when they are an integral part of a microgrid with a high-level control functionality.

The first part of the seminar will present an overview and perspectives of energy storage technologies, with the main focus on battery systems. The second part will be devoted to developments of power semiconductor converter systems that are aimed to be a part of the interface of relatively low DC voltage of the batteries with the grid.

Bios:

Andrei Blinov received the B.Sc. and M.Sc. degrees in electrical drives and power electronics and the Ph.D. degree, with a dissertation devoted to the research of switching properties and performance improvement methods of high-voltage IGBT-based DC-DC converters, from Tallinn University of Technology, Tallinn, Estonia, in 2005, 2008, and 2012, respectively. He is currently a Senior Researcher at the Department of Electrical Engineering, Tallinn University of Technology. His research interests are in modelling and research of switch-mode power converters, advanced modulation techniques, new power semiconductor device technologies and semiconductor heat dissipation aspects.

Roman Kosenko received the Dipl. Eng. and M. sc. degrees in Electronics from the Department of Industrial Electronics, Chernihiv State University of Technology, Chernihiv, Ukraine, in 2011 and 2013, respectively. He is currently working toward the Ph. D. degree at the Power Electronics Group, Department of Electrical Power Engineering and Mechatronics, Tallinn University (Estonia), and at the Biomedical Radioelectronic Apparatus and Systems Department of Chernihiv National University of Technology (Ukraine). His fields of interest include research, design and simulation of switch mode converters for distributed power generation systems. He is author or co-author of 25 scientific papers and is the holder of three utility models in the field of power electronics.
